Tigers haven't been beaten since Good Friday, when they went lost by seven points at Maher Oval. They won the return encounter by 15 points and then the second semi-final by nine.

But the Bulldogs have won the last two grand finals and confirmed their potential with a 10-goal thrashing of Leeton-Whitton (and 12 players sharing in 17 goals) last week.

They'll look to players with senior experience to help them end Tigers' hot streak, including Angus Grigg and Ben Lewington, while Max Von Marburg has kicked 51 goals in the 17.5s this season.

Tigers coach, and club legend, Steven Priest said he's not putting any pressure on his team, which didn't make finals last year.

"This year it's a positive having numbers. We had an influx of kids coming in, and most of our guys stayed around and are a year older, that's probably the main reason (for the success)," Priest said.

"We haven't got any flash players, we've just got a team of guys who are having a go, enjoying their footy and enjoying playing with their mates.

"I don't put a lot of pressure on them. I just want them to have fun.... most of these boys have been together since the Under 10s and hardly any have been in a final, or had any success. To make a grand final, they've got an opportunity now."

Centre-half-back Will Adams and Doug de Jong in the centre have been among their important contributors, along with Hamish Gilmore (28 goals, plus four senior games, and runner-up in the league medal), while Cooper Pavitt and Sam McNaughton also add spark.

Tigers' last win in the under age competition was in 2014, against Mangoplah-Cookardinia United-Eastlakes.
